You keep pushing the 4200 but nobody is listening...


Main reasons are:

1) its different.
2) a near stock 4200 with a chinese turbo is a 450 hp engine.

LS engine swaps are everywhere, just like every one with a SBC had a holley carb, Edlebrock intake and some brand of headers in years past.

This is the inliners right? dedicated to all inline engines.

The reaction that people get to a 4200 swap is a crowd of folks trying to figure out what it is... try asking some of the others that had done the swap.

I've discussed this topic with a few inliners over the years including Tom L. and the more common theme was the assumption that there is no support for the 4200 is no longer true.
